Résumé

The annual Random Stratified Trawl Survey was undertaken in Division 58.5.2 in the vicinity of Heard Island during May 2015. This paper provides a preliminary assessment of mackerel icefish population structure, abundance and yield for the area of Division 58.5.2 to the west of 79o 20’ E using standard CCAMLR methods. A large 2+ cohort is dominating the population. These projections indicate that catches of 482 t in the 2015/16 season and 357 t in the 2016/17 season.
